Segmental left ventricular (LV) dysfunction associated with subarachnoid hemorrhage usually develops in the apex. We encountered a patient with subarachnoid hemorrhage associated with transient LV basal dysfunction and functional mitral regurgitation. Echocardiography showed akinesis in the whole basal LV and hyperkinesis in the apex with significant mitral regurgitation without organic leaflet lesion. The LV wall motion abnormality as well as mitral regurgitation disappeared 22 days later. Subarachnoid hemorrhage can occasionally cause atypical segmental basal LV dysfunction associated with functional mitral regurgitation.
